.ToaZZ whom, it may concern:

broken away in order to display the rubber` gasket i in position inits recess in the circular portion of the frame F, and one of its radial arms H; and Fig. 2, a central vertical section of the whole apparatus, including the shade to be silvered. I

The letter A indicates the shade, which is blown of glass, in one piece, and its lower edge rests upon the rubber gasket i', which is in yannular form, and is seated in a recess of like form in the circular portion of the frame F, as shown, and eis a like annular gasket or collar, which is provided with a .proper seat in the cap E, and is pressed down upon the upper edge of the shade, so as to make a liquid-tight joint therewith, by the cap E, the screw-shaft D, and`its nut n. The lower end ofthe screw-shaft D is provided with a thread, and is screwed into the threaded hole in the center piece, I, of the frame.

B is an outer shell, made of wood or other suitable material, made to surround the shade, with its lower edge upon the rubber gasket i',

so as to leave the space C between it and the shade, with openings f above, through which side ofthe lower edge of the jacket. or shell B, anda is a circular clamping-frame, provided with binding-screws b, by means of which the lower edge of the jacket B is compressed with the forcel required between the main frame and the ring d, to make a liquidtight jointbetwe'en the shell and the gasket.
